Specification of Letters Patent.

Application filed January 12, 1915. Serial No. 1,?6'7.

To all whom it may concern: I

Be it known that I, WILLARD N. Pncnnn, a citizen of the United States, IGSlClll'lg at the city of Los Angeles, county of Los An geles, State of California, have invented In the drawings forming a part of this application I have illustrated my invention as applied to an amusement device and will so describe it but donot desire to limit my self to such device as the power principle is applicable to many other uses.

Figure 1 is a side elevation of an amusement device for viewing the landscape with the partsthereof in their balanced pos tion. Fig. 2 is a plan view of the operating part of the device. Fig. 3 isanend view of the weights detached. Fig. l is a diagrammatic view of a position of the weight operating mechanism. 1

In the drawings 10 and 11 are the side members of the base or supporting frame in which is mounted the movable frame which consistsof the side members and 18 and the transverse brace membersll' and side brace members 15. The movable frame is revolubly mounted intermediate its ends atthe top of the base frame byapipe 16 the ends of which project into caps 17 and 18. These caps are secured to the base frame and a fluid-tight joint is provided between pipe 16 and the caps but the interior of the caps and pipe are in communication. In pipe 16 preferably at the center is a partition 19 which divides the interior of the pipe into two chambers. Cap 17 is connected by pipe 22 with one end of a hydraulic pump 28. The other end of pump 23 is con nected by pipe Ql with cap 18. Pump 23 is operated by lever 25 which is suitably connected to piston stem 26 of the pump. On pipe 16 preferably, at the center is mounted a two way hydraulic jack 27 one end of which is connected with chamber 20 and the other end of which is connected with chamber 21 by pipe 28.

In the longer end of the movable frame is mounted a swinging passenger cage 29. In the shorter end of the movable frame are mounted the shifting weights 30 and 81. These weights comprise receptacles which are preferably constructed of sheet metal shaped into segments of hollow cyl inders and form the jackets of the weights. The interior of each 3acket is filled with suitable material, such as sand which has weight and is easily put into place after the sheet metal parts are positioned. Suitable filling ports covered by movable caps 32 and 33 are provided for that purpose. At each end of the'jackets are cars 8i by means of which the weights are pivotally mounted on the shorter end of the movable frame by shaft .35. from the edges of the weights are cable carrying frames 36 which with the curved surfaces of the jackets form circles. Wei ght' from its outermost to its innermost points will cause the rotation of the weights a half turn. They are also secured to each carrylng frame at one point to prevent slipping.

- A'bralre drum 39 is secured to the moving frame around pipe 16 and a brake band 4:0 passes around said drum, one end of which is secured to the base frame and the other to brake lever 41 mounted on said base frame.

In the operation of my apparatus as a pleasure device with the parts in the position of Fig. 1 they balance. By means of a rope 42 the cage is brought to the ground and the desired load of passengers enters the cage. The weights are then shifted totheir outermost position which is directly opposite the position shown in Fig. 1. In this position the weights have a little greater lifting power than the weights of the load and the resistance caused by the friction of the moving parts. The bearings will be ball bearings to reduce the friction to the minimum. The cage in its upward move- Patented Dec. 7,1915.

Extending centrally the cage travels back. The operation is repeated as often as desired.

A derrick for unloading or loading ships can be constructed by using the cage to transport the freight. Water buckets can be used instead of the cage to lift water from v .one elevation to another. I

It will be seenthat by shifting the position of the Weights from their innermost toward their outermost positions the lifting power of the weighted end of the lever increases until the maximum power is reached by the weights attaining their outermost position. It will also be observed that the weights are connected so as to move together and that one moves downwardly thereby producing power while the other moves upwardly thereby requiring power to lift it, but the power produced by the down wardly moving weight produces the power to lift the other weight and as the weights are balanced against each other, to shift the weights it is only necessary to use enough -,1. In a power, machine a movable lever pivoted intermediate its ends; two weights shiftably mounted on one of the ends of said lever at points equidistant from the fulcrum of said lever, said lever being balanced when said weights are' shifted to their innermost position; and means for shifting the positions of said weights.

2. In a power machine a base frame; a movable frame pivotally mounted intermediate its ends in said base frame; two weights shiftably mounted on one of the ends of said movable frame at points equidistant from the pivot of said movable frame; a load carrying attachment on the other end of said movable frame," said movable frame being so mounted in said base frame that when the weights. thereon are shifted to their innermost position the parts are balanced; a brake on said movable frame; and means to shift said weights.

3. In a power machine a base frame; a movable frame pivotally mounted intermediate its ends in said base frame; two weights shiftably mounted on one end of said movable frame atpoints equidistant fromthepivot of said movable frame; a

load carrying attachment on the other end of'said movable frame, said movable frame being so mounted in said base frame that whenthe weights thereon are shifted to their mnermostposition the parts are balanced;

a brake on said movable frame; and a hydraulic jack mounted on said movable frame and operatively connected to said weights, whereby when said jack is operated said weights can be shifted; and a hydraulic pump operatively connected to said jack whereby said jack may be operated in either of two directions, by operating said'pump.

In witness that I claim the foregoing I have hereunto subscribed my name this 15th day of December, 1914.
